If the issue has not cleared you will certainly need some professional help.

If after having your system tested it’s found that the inverter is the problem you have two options:

  1. Get the faulty inverter repaired.
  2. Replace the faulty unit with a good quality replacement inverter.

If you decide to have the inverter repaired you’re still going to spend a lot of money and have an inferior quality product that’s not covered by any warranty. The Sunny Roo, Beyond Building & Sunna inverter manufacturer is no longer around as they went into liquidation a few years ago so any warranty will no longer be honored. We recommend having the faulty unit replaced with a quality new inverter that has a full 5 or 10 year warranty – it may initially cost a bit more but in the long term it will certainly provide you with the best value for money.
